Specification of Letters Patent. Paientd June 13, 1916.

Application filed July 28, 1914. Serial No. 853,782.

To all whom t may concern.'

Be it known that I, JAMES J. QUINN, a.v citizen of the United States,residing at 1613 Twelfth street, Eddystone, in the county of Delawareand State of Pennsyl- Vania, have invented new and useful Improvementsin Mosquito and Fly Stops for Windows, of which the following cation. A

This invention is an improved stop for use on the under side of an outerwindow sash to prevent flies and mosquitosfrom entering the room whenthe inner sash is raised part way and an ordinary fly screen is arrangedbelow said inner sash, the object of the invention being to provide animproved article of this character which is extremely cheap and simpleand whichmay be readily attached. to or detached from the lower side ofthe upper sash.

The invention consists in the construction and arrangement of deviceshereinafter described and claimed.

In the accompanying drawings Figure 1 is a horizontal sectional view ofa window provided with a fly and mosquito stopconstructed in accordancewith my invention, and looking upwardly. Fig. 2 is a vertical sectionalview of the same on the plane indicated by the line 2-2 of Fig. 1. Fig.3 is 'a detail perspective view of the stop. Fig. 4 is a detailsectional view of a modified form of the stop. Fig. 5 is a transversesectional view of the same on the plane indicated by the line 5-5 ofFig. 4.

For the purposes of this specification the sides of a window frame areindicated at l, the outer sash is indicated at 2 and the inner sash isindicated at 3.

In accordance with my invention I provide a wiper strip or bar 4 whichin the form of my invention shown in Figs. 1 2-3 is made of rubber andin the form of my invention shown in Fig. 4 is formed by a wire screenstrip 5. The wiper strip or bar is partly inserted between the upper andY lower webs 67 of a sheet metal attaching bar 8 which is doubled andbent longitudinally so that a bight 9 is formed between the said web andwhich presents a rounded outer edge on said attaching bar. The webs 6-7bear against each other for about halfway across the attaching bar fromthe outer side, as at 10 and the lower web 7 is is a specioffset as at11 to form a space between said offset portion and the upper web 6 for.the reception of the wiper strip or bar 4. rI`he attaching barl isprovided with openings for the reception of screws or other like devices13 by means of which the attaching bar is securedto the lower side ofthe bottom bar of the upper, outer sash 2 so as to cause the inner edgeof the inwardly extending wiper strip 4 to bear against the glass pane14 of the inner sash. I-Ience the space between the sashes, when thelower sash is raised and a fly screen is placed thereunder, is closed bythe wiper strip 4 and entrance of flies, mosquitos and other ynoxiousinsects is effectually prevented. .v

My improved fly andmosquito stop is extremely cheap and simple, isentirely effective and may be readily attached to or removed from awindow.

In the form of my invention shown in Figs. 4 5 the attaching barcomprises a central portion 8a and end members 8b which aretelescopically related thereto and may be adjusted to enable the bar toiit a window able frame bars, said bars comprising a cen- Y tral sectionhaving end sections telescoping therein, means for fastening said barsto the lower edgeof an outer'window sash, reticulated strips having theinner edgesV thereof secured to overlapping portions of said bars, andhaving the free edges thereofnor-Y `mally in contact with the glass paneof a '0- operating sash.
